It has stable size, good appearance and color, better impact strength, fluidity, heat resistance and medicine resistance.
Description
Technical field
The present invention relates to a kind of nylon and ABS alloy material that improves impact property and resistance toheat, relate in particular to a kind of nylon and ABS alloy material that improves impact property and resistance toheat of a kind of injection moulding automobile wheel cover, panel board circle frame, safety lever, sports apparatus and other motor products.
Technical background
Nylon/ABS alloy is released by the Borg Warner Chemicals company and the Monsanto company of the U.S. the earliest, has heat-drawn wire than PA height, and the higher characteristics of vicat softening temperature, thereby become the ideal material of making trolley parts such as body of a motor car coverboard.
Advantages such as PA6 has wear-resisting, anti-solvent, oil resistant, use temperature are wide, but have also that water-absorbent is big, deficiency such as poor dimensional stability, low temperature and dry state shock strength are low, limited its use greatly.With PA6 and ABS blend, can make the toughness of existing ABS, again the alloy of thermotolerance and the oil-proofness of PA be arranged.This kind alloy is widely used in automobile, electronic apparatus, home-use device etc.But because the polymkeric substance that PA6 is a kind of crystallinity, strong polarity, melt viscosity is very low, and ABS is the polymkeric substance of a kind of amorphism, low-pole, the solubility parameter of the two differs bigger, it is incompatible to belong to thermodynamics, simple worker mixes and causes two-phase interface tension force very big, thereby cause mechanical property relatively poor, thereby will obtain nylon with practical value/ABS alloy material, must carry out morphology Control and interface modification.
Summary of the invention
The object of the present invention is to provide a kind ofly have that dimensional stabilizing, high strength, outward appearance are good, the nylon that improves impact property and resistance toheat and the ABS alloy material of high workability, resistance to chemical reagents.
For realizing above purpose, technical scheme of the present invention provides a kind of super tough heat-resisting nylon and ABS alloy material, and it is made up of a mixture, and its weight proportion consists of:
Nylon 6 slice 20-70%
ABS 25-70％
SAN 5-30％
Heat-resistant agent 1-15%
Compatilizer 1-20%
Oxidation inhibitor 0.1-1%
Lubricant 0.1-0.5%
Wherein the relative viscosity of nylon 6 slice is 2.4-3.8PaS; ABS is vinyl cyanide, divinyl and styrene copolymer, and its rubber content is 35%-70%; SAN is the multipolymer of vinylbenzene and vinyl cyanide, and its melting index is 15-40g/10min; Heat-resistant agent is maleimide and derivative thereof, can be bismaleimides, N-phenylmaleimide; Compatilizer is the polymer A grafted maleic anhydride, can be SMA, ABS-g-MAH; Wherein polymer A can be PS, AS, ABS; Oxidation inhibitor comprises a kind of Hinered phenols antioxidant, can be 1076 and the compound system of a kind of Hinered phenols antioxidant and phosphite ester kind antioxidant, can be 1010/168 (1: 1); Lubricant is the ultra-high molecular weight polysiloxane.
The nylon and the ABS alloy material preparation technology that improve impact property and resistance toheat are: each component is put into the high mixer kind in proportion mixed 2-5 minute, use the screw extrusion press extruding pelletization then, processing temperature is at 180-260 ℃, and the screw rod revolution is at 180-600 rev/min.
Advantage such as PA6 has wear-resisting, anti-solvent, oil resistant, use temperature are wide is the engineering plastics of current production rate maximum.
The acrylonitrile/butadiene/styrene terpolymer has been gathered rigidity that glossiness that vinylbenzene has and formability, vinyl cyanide have and resistance to chemical reagents and excellent mechanical property, shock-resistance that divinyl has, can improve dimensional stability, shock strength, chemical resistant properties and the processing characteristics of nylon with nylon blending.
SAN has excellent flowing performance and anti-medicine performance and rigidity.Compatible with the nylon part in system, can improve the rigidity and the flowing property of alloy material.
Because nylon and ABS belong to the thermodynamics incompatible material, the adding of styrene/acrylonitrile/copolymer-maleic anhydride can greatly improve both consistencies, improve the shock strength and the elongation at break of material, but because the fragility of vinylbenzene, vinyl cyanide and copolymer-maleic anhydride self, add excessive vinylbenzene, vinyl cyanide and copolymer-maleic anhydride and can reduce the impact property of material on the contrary, relatively Shi Yi addition is 1-20%, and better addition is 3-15%.
Oxidation inhibitor comprises a kind of Hinered phenols antioxidant, can be 1076, is mainly used in the oxidation that prevents ABS/SAN and the compound system of a kind of Hinered phenols antioxidant and phosphite ester kind antioxidant, can be 1010/168 (1: 1), mainly prevents the oxidation of PA6.
The ultra-high molecular weight polysiloxane improves the materials processing flowability as lubricant, reduces frictional coefficient, improves smooth property, improves surface luster.
The present invention adopts nylon 6 and ABS resin, make a kind of super-toughened nylon/ABS alloy material, solve the size instability of nylon material, the shortcoming of easy warpage well, and the inconsistent characteristics of thermodynamics of nylon 6 and ABS material, prepared a kind ofly have that dimensional stabilizing, intensity height, outward appearance are good, the super-toughened nylon/ABS alloy material of high workability, resistance to chemical reagents.
Advantage of the present invention is the characteristic that has had nylon 6 and ABS concurrently, and scantling is stable, the intensity height, and outward appearance is good, high workability, resistance to chemical reagents.
